Description

[Technical Field]

[0001] The present invention relates to an indoor air conditioning control system and an indoor air conditioning control method that can control air conditioning according to the comfort level of the residents. [Background technology]

[0002] Traditionally, in buildings such as office buildings and commercial facilities, packaged air conditioning systems, such as multi-split air conditioning systems that allow multiple indoor units to be connected to a single outdoor unit, have been widely adopted. In particular, multi-split air conditioning systems have become the mainstream air conditioning equipment in buildings because each indoor unit can be individually temperature-controlled and cooling and heating can be switched within the same system. In this type of packaged air conditioner, a temperature sensor built into the indoor unit detects the temperature of the air returning from the room, and controls the unit to match the set temperature set by a remote control installed outside the living area.

[0003] With this control method, the temperature sensor built into the indoor unit is not very accurate, so the temperature detected by the indoor unit may not reflect the temperature felt by the occupant. As a result, the occupant needs to frequently change the temperature setting on the remote control to improve their comfort. As a technology to solve this problem, Patent Document 1 describes an air conditioning control method that involves installing a temperature sensor in the living area and a setting terminal capable of setting the temperature with the same accuracy as the temperature sensor to change the set temperature of the indoor unit.

[0004] On the other hand, in recent years, air conditioning control based on PMV, an indoor environmental index that indicates the comfort level of residents, is also being adopted (see Patent Documents 2 and 3). PMV is an index calculated by comprehensively considering environmental factors such as room temperature, humidity, airflow velocity, and radiant temperature, as well as human factors such as clothing amount and metabolic rate, and can more appropriately represent the comfort level of residents. In particular, advancements in IoT and sensor technology have made it possible to acquire environmental data such as temperature, humidity, airflow velocity, and radiant temperature with lower costs and higher accuracy. This has made it easier to calculate PMV and to finely control each environmental factor, leading to the widespread implementation of PMV-based control. In addition to PMV, other indoor environmental indices such as SET* and PET have also been proposed to indicate comfort. [Prior art documents] [Patent Documents]

[0006] While conventional air conditioning systems, including the aforementioned packaged air conditioners, are often controlled by a building management system (BMS) that centrally manages the entire building, these control technologies rely on temperature detection by temperature sensors built into the indoor units or the room temperature itself. They do not utilize diverse indoor environmental indicators that represent occupant comfort, and therefore do not achieve air conditioning control tailored to occupant comfort.

[0007] The present invention aims to provide an indoor air conditioning control system and an indoor air conditioning control method that can control air conditioning in accordance with the comfort of the residents. [Means for solving the problem]

[0008] To achieve the above objective, the indoor air conditioning control system of the present invention provides an air conditioning set temperature T supplied from the outside. * iSVAccording to the above, an air conditioning system that controls the indoor air conditioning temperature, and from the indoor environment numerical values obtained from the environmental sensors installed in the indoor space, based on the indoor environment indicators, the indoor target temperature T aSV is calculated by the indoor target temperature calculation means, the indoor temperature T a obtained from the environmental sensor and the indoor target temperature T aSV are used to calculate the air conditioning target set temperature T iSV by the air conditioning target set temperature calculation means, and the air conditioning set temperature T * iSV value is output to the air conditioning system as the air conditioning target set temperature T iSV .

[0012] The indoor air conditioning control method and indoor air conditioning control system of the present invention will be described in detail below with reference to the drawings.

[0013] [Example 1] <1> Overview of an air conditioning system to which the present invention is applied The indoor air conditioning control method and indoor air conditioning control system of the present invention are applicable to commonly used air conditioning systems. In this embodiment, the air conditioning system S provides air conditioning to the indoor (living area) L using an air conditioner 1 (indoor unit) connected to an outdoor unit (not shown). The air conditioner detects the indoor temperature T using a temperature sensor 2 built into the main body of the air conditioner 1, which detects the temperature of the air returning from the room. i Detected as, Air Conditioning Detection Indoor Temperature T i However, the air conditioner set temperature T input from the outside to the air conditioner set temperature acquisition unit 11 * iSV This is a packaged air conditioner that controls the indoor air conditioning temperature L in such a manner. The air conditioning system S can communicate using conventional communication protocols such as BACnet, and is connected to the controller 3 via a communication line to enable transmission and reception, and the air conditioning system detects the indoor temperature T i The data is sent to controller 3, and the air conditioning set temperature T * iSV This is received from controller 3.

[0014] <2> Environmental sensors An environmental sensor 4 is installed in the room L, and the indoor temperature T aAn indoor environmental value N consisting of humidity, radiant temperature, and airflow velocity is detected. The environmental sensor 4 may be divided into multiple units depending on the type of value to be detected. The environmental sensor 4 is connected to the controller 3 via a communication line, similar to the air conditioning system S, and the indoor temperature T a The indoor environment values ​​N are sent to the controller 3.

[0015] <3> controller Controller 3 is, for example, a conventional PLC, and is connected to the air conditioning system S and environmental sensor 4 via a communication line. Controller 3 receives the indoor temperature T detected by the air conditioning system S via the temperature sensor 2 built into the main unit of the air conditioner 1. i The air conditioning detection indoor temperature acquisition unit 31 acquires the indoor temperature, the indoor environment numerical value acquisition unit 32 acquires the indoor environment numerical value N from the environmental sensor 4, and the indoor temperature T a The indoor temperature acquisition unit 33, which acquires the indoor temperature T, is connected to the air conditioning detection indoor temperature acquisition unit 31 and the indoor environment numerical value acquisition unit 32, and the indoor temperature T a Based on other indoor environmental values ​​such as N, the target indoor temperature T aSV The indoor target temperature calculation unit 34 calculates the indoor target temperature T, and the air conditioning detection indoor temperature acquisition unit 31, indoor temperature acquisition unit 33 and indoor target temperature calculation unit 34 are connected. aSV、 Air conditioning detection indoor temperature T i and indoor temperature T a From the target temperature setting of the air conditioning T iSV The air conditioning target temperature calculation unit 35 calculates the air conditioning target temperature T, and the air conditioning target temperature calculation unit 35 is connected to the air conditioning target temperature calculation unit 35. iSV Set the air conditioning temperature to T * iSV It includes an air conditioning set temperature output unit 36 ​​that outputs to the air conditioning system S.

[0016] <4> User-configured terminal The user setting terminal 5 is installed in the room L, etc., and is used to set the clo value and met value for calculating the PMV value of the room L and the target PMV value. The target PMV value, clo value, and met value set by the user configuration terminal 5 are sent to the controller 3 via communication or other means.

[0017] <5>Calculation of the air-conditioning target set temperature T iSV of The calculation of the air-conditioning target set temperature T by the controller 3 iSV is performed according to the following steps.

[0018] <5.1>Indoor target temperature calculation step Based on the indoor environmental value N obtained from the environmental sensor 4, the clo value, met value, and target PMV value set on the user setting terminal 5, the indoor target temperature T of the indoor L is calculated by the indoor target temperature calculation unit 34 aSV [[ID=十七]]to calculate. Note that there are multiple environmental sensors 4 in the indoor L to be air-conditioned. When obtaining the indoor environmental value N from multiple environmental sensors 4, for example, the value referred to by the PMV control algorithm is obtained by the following method. ·Average value... Calculate the average value of the indoor environmental values N of the multiple environmental sensors 4. ·Median value... Refer to the median value of the indoor environmental values N of the multiple environmental sensors 4. ·Minimum value... Refer to the minimum value among the indoor environmental values N of the multiple environmental sensors 4 (especially during heating). ·Maximum value... Refer to the maximum value among the indoor environmental values N of the multiple environmental sensors 4 (especially during cooling). ·Weighted average... Increase the weight of the indoor environmental value N of the environmental sensor 4 located at the location where the occupancy sensor provided separately for the multiple environmental sensors 4 reacts. The indoor temperature T a in <5.2> below is the same.

[0019] <5.2>Air-conditioning target set temperature calculation step The indoor temperature T obtained from the environmental sensor 4 a , the air-conditioning detected indoor temperature T detected by the temperature sensor 2 built in the main body of the air conditioner 1 i and the indoor target temperature T obtained by the indoor target temperature calculation step aSV are substituted into the following formula (1) to calculate the air-conditioning target set temperature T iSV to calculate.

[0020] T iSV = T aSV + a×(T i - T a ) + b····(1) Here, a and b are constants as shown below.

[0021] a is the proportional gain for proportional control. Depending on the positions of the temperature sensor 2 of the air conditioner 1 and the environmental sensor 4 in the room L, the responsiveness to the operation of the air conditioner 1 varies. If the response of the environmental sensor 4 in the room L is faster than that of the temperature sensor 2 of the air conditioner 1, it is conceivable that the room L is locally air-conditioned and the surrounding air conditioning becomes insufficient. In this case, set a to be less than 1. Conversely, if the response of the environmental sensor 4 in the room L is slower than that of the temperature sensor 2 of the air conditioner 1, it is conceivable that excessive heat treatment occurs near the temperature sensor 2 of the air conditioner. In this case, set a to be 1 or more.

[0022] b is a control offset for correcting the deviation. There are two deviations to be corrected. The first is the correction of the individual difference in the detected values of the room temperature T by the temperature sensor 2 of the air conditioner 1 and the environmental sensor 4. a The temperature sensor 2 of the air conditioner 1 is used without being calibrated for a long time, and since a large number of environmental sensors 4 are installed, inexpensive sensors are used, and individual differences may occur. These differences can be addressed by calculating the deviation by installing the environmental sensor 4 at the same location once.

[0023] The second is the deviation from the target value of the air conditioning control. For example, when the air conditioner 1 is under ON / OFF binary control, usually a dead zone (operation gap) is provided with respect to the set temperature. If this dead zone is too wide for the variation of the room temperature Ta in the room L, a situation is assumed where the air conditioner 1 is not immediately turned ON / OFF even if the PMV value deteriorates. At that time, in order to narrow the dead zone, for example, when performing heating control, the air conditioning target set temperature T iSV can be adjusted to be increased by adding the deviation b.

[0024] Furthermore, depending on the control method inside the air conditioner 1, there may be multiple operating modes. For example, there may be three modes: a "high-load mode" that reaches the set temperature quickly with high-load operation when the difference between the set temperature and the current room temperature is large, such as when the air conditioner is started up; a "low-load mode" aimed at maintaining the room temperature when the set temperature is close to the current room temperature; and a "fan mode" used when the demand for heat treatment is low and the air conditioner would be over-cooled even in low-load mode. It is believed that a dead zone is present in the temperature difference set for switching between these modes. Therefore, by using deviation b, it is possible to intentionally change the operating mode. Since this depends on the control method of the air conditioner 1, the control period and deviation b of the PMV control algorithm should be appropriately determined according to the air conditioning system S used.

[0025] <6> Air conditioning set temperature T * iSV Changes The air conditioning target temperature T calculated in the air conditioning target temperature calculation step iSV The air conditioning set temperature T is output from the air conditioning set temperature output unit 36. * iSV This data is then sent to the air conditioner set temperature acquisition unit 11 of the air conditioning system S. Then, the air conditioning system S detects the indoor temperature T. i The air conditioning set temperature is T * iSV The indoor air conditioning temperature is controlled to achieve the following:

[0026] As described above, the air conditioning set temperature T of air conditioner 1 * iSV This is the target air conditioning temperature T calculated by an algorithm based on PMV. iSV This will be changed. As a result, it will be possible to achieve air conditioning control that is tailored to the comfort of the residents. In addition, by performing air conditioning control based on PMV, the energy consumed by air conditioning control can be optimized.

[0027] [Example 2] <1> Overview of an air conditioning system to which the present invention is applied In the above-described embodiment 1, the air conditioning system S communicates to detect the indoor temperature T. i or air conditioning set temperature T * iSV Although it is possible to send and receive data, the air conditioning system S in this embodiment is unable to communicate. The air conditioning system S, similar to Example 1, uses an air conditioner 1 (indoor unit) connected to an outdoor unit (not shown) to provide air conditioning to the indoor (living area) L. A temperature sensor 2 built into the main body of the air conditioner 1 detects the temperature of the air returning from the room, and the air conditioning system detects the indoor temperature T. i Detected as, Air Conditioning Detection Indoor Temperature T i The air conditioning set temperature T is set by the air conditioning control terminal 6 installed inside the room or elsewhere. * iSV The system controls the indoor air conditioning temperature L in such a manner.

[0028] <2> Environmental sensors Similar to Example 1, an environmental sensor 4 is installed in the room L, and the room temperature T a An indoor environmental value N consisting of humidity, radiant temperature, and airflow velocity is detected. The environmental sensor 4 may be divided into multiple units depending on the type of value to be detected. The environmental sensor 4 is connected to the controller 3 via a communication line, similar to the air conditioning system S, and the indoor temperature T a The indoor environment values ​​N are sent to the controller 3.

[0029] <3> controller Similar to Example 1, the controller 3 is, for example, a conventional PLC, and is connected to the environmental sensor 4 via a communication line. The controller 3 in this embodiment includes an indoor environment value acquisition unit 32 that acquires indoor environment value N from the environmental sensor 4, and an indoor temperature T from the environmental sensor 4. a The indoor temperature acquisition unit 33, which acquires the indoor temperature T, is connected to the indoor environment numerical value acquisition unit 32. a Based on other indoor environmental values ​​such as N, the target indoor temperature T aSVThe indoor target temperature calculation unit 34 calculates the indoor target temperature T, and the indoor temperature acquisition unit 33 and the indoor target temperature calculation unit 34 are connected. aSV and indoor temperature T a From the target temperature setting of the air conditioning T iSV The air conditioning target temperature calculation unit 35 calculates the air conditioning target temperature T, and the air conditioning target temperature calculation unit 35 is connected to the air conditioning target temperature calculation unit 35. iSV Set the air conditioning temperature to T * iSV It has an air conditioning set temperature output unit 36 ​​that outputs as [a specific value].

[0030] <4> User-configured terminal Similar to Example 1, the user setting terminal 5 is installed in the room L, etc., and is used to set the target PMV value for the room L, as well as the clo value and met value for calculating the PMV value. The target PMV value, clo value, and met value set by the user configuration terminal 5 are sent to the controller 3 via communication or other means.

[0031] <5> Air conditioning target setting temperature T iSV Calculation In this embodiment, the target temperature T of the air conditioning in the controller 3 iSV The calculation is performed using the following steps.

[0032] <5.1> Steps for calculating indoor target temperature Similar to Example 1, the indoor target temperature calculation unit 34 calculates the indoor target temperature T of the room L based on the PMV control algorithm using the indoor environment value N obtained from the environmental sensor 4 and the clo value, met value, and target PMV value set in the user setting terminal 5. aSV Calculate.

[0033] <5.2> Step for calculating the target temperature for air conditioning The indoor temperature T obtained from the environmental sensor 4 a and the indoor target temperature T obtained by the indoor target temperature calculation step aSV Compare the following and determine the target air conditioning temperature T using either equation (2) or (3) shown below. iSV Calculate.

[0034] Indoor temperature Ta<indoor target temperature T aSV At that time, Air conditioning target setting temperature T iSV =Air conditioner set temperature T *iSV +ΔT…(2)

[0035] Indoor temperature Ta > Indoor target temperature T aSV At that time, Air conditioning target setting temperature T iSV =Air conditioner set temperature T *iSV -ΔT…(3)

[0036] In equations (2) and (3), ΔT is the range of set temperatures that are changed at regular intervals (control cycles), and the minimum resolution depends on the resolution of the set temperature of the air conditioner 1. Specifically, the minimum resolution that can be input via the air conditioner control terminal 6 (for example, the value that changes with a single press of the temperature adjustment button) is set as ΔT. Furthermore, if the control period ΔT is set to an extremely short control period, the target temperature T for air conditioning will be lowered. iSV Because problems with the temperature rising too high or falling too low can occur, a duration of 5 to 15 minutes is preferable, but the target temperature setting for the air conditioning is T iSV The appropriate response time for the operation of the air conditioner 1 to changes in the environment, the response time to changes in the indoor environment, etc., will be determined as appropriate.

[0037] <6> Air conditioning set temperature T * iSV Changes The air conditioning target temperature T calculated in the air conditioning target temperature calculation step iSV The air conditioning set temperature T is output from the air conditioning set temperature output unit 36. * iSV This information is then sent to the air conditioner control terminal 6. If the air conditioner control terminal 6 is capable of communication, the air conditioner set temperature T * iSV Enter the following: If communication is not possible, for example, the air conditioner operating terminal 6 can be mechanically operated to change the set temperature using the setting control device 61, which allows you to change the set temperature T. * iSV The user inputs the value and uses the setting control device 61 to operate the air conditioner control terminal 6 to change the set temperature.

[0038] [Other examples] <1> Indoor environment index While the above-described examples 1 and 2 use algorithms based on PMV to control the air conditioning, air conditioning control may also be performed using thermal indices such as SET* or PET, which are indoor environment indices that represent comfort other than PMV. In both cases, by controlling the air conditioning based on indoor environmental indicators, the energy consumed by the air conditioning can be optimized. Furthermore, indoor environmental indicators are not limited to PMV, SET*, PET, etc., which represent comfort levels. Air conditioning control may also be based on indicators such as the mold index, which represents the likelihood of mold growth. When using the mold index, indoor temperature and humidity are obtained as the indoor environmental value N.

[0039] <2> Applicable air conditioning systems In the above-described Examples 1 and 2, the air conditioning system S to which the present invention is applied was targeted at the temperature setting of the air conditioner (indoor unit) 1 in a packaged air conditioner. However, it is not limited to this and can be applied to various air conditioning systems, such as radiant panels in radiant air conditioning systems, and temperature settings of air conditioners in single-duct systems and double-duct systems.
